Smith recommends reseeding lawns in the fall to prevent weed growth. Since many weeds are already dead late in the season, there is less competition for space as grass seeds try to take root. Smith also recommends strong, high-quality grass seed. Look for the highest germination and purity percentages available.
A rototiller is generally recommended for yards greater than 300 square feet. Its rotary tines break up the lawn and churn the soil as you guide it in the right direction. Gas-powered rototillers tend to be noisier than electric rototillers, which are plugged in and conveniently start at the push of a button.
Rotoscoping in the digital domain is often aided by motion tracking and onion-skinning software. Rotoscoping is often used in the preparation of garbage mattes for other matte-pulling processes. Rotoscoping has also been used to create a special visual effect (such as a glow, for example) that is guided by the matte or rotoscoped line. A classic use of traditional rotoscoping was in the original three Star Wars movies, where the production used it to create the glowing lightsaber effect with a matte based on sticks held by the actors.
